What is the hive thinking about incentives for subjects who are in multiple states and can be disbursed easily and leave an audit trail.

I am doing some background work on this for a colleague. She is reimbursing people small amounts for taking a survey. these are individuals with lived experiences of mental illness, on disability, or lower income. It would need to be something electronic --don' t wish to mail gift cards again-- and something that an IRB and university office of research would approve as it leaves an audit trail.

I've been thinking Amazon, e card but know that that is not always what people like. I've thought Target since target is across the US, ditto walmart, although walmart is hard to get to for some people in the city to get to.

It would be nice to have options so that people can buy food.

We may be able to offer more than one type e.g. amazon or target or wall mart, but not sure.

thanks in advance for thoughts. I find this stuff to be the bane of being a PI on any project.
